heres a bit of info i chanced on today. if an employee is swinging the lead in any way, days off happening often or working slow refusal to climb - you suspect fakery -you can demand said worker goes to their doctor and has a full check up followed by a fitness to work statement from said doc

a restaurant i dine in has a young employee refusing to wash up says her back plays up and refusing a string of tasks now ordered to get the docs report on her- shes stalling right now but im following the case
